New version of Hybrid PhysX mod was released today by GenL – yet another round of confrontation between Hybrid PhysX community and NVIDIA.

Release Notes:

1.05ff – 26/10/2011:
- added support for fixing new limitations introduced in 285.xx drivers and PhysX System Software 9.11.0621
- mod will now delete all application 3D settings profiles from NVIDIA Control Panel (prevents problems with known PhysX games)
- updated old patterns

As revealed in latest interview, NVIDIA still has no plans to support AMD + NV PhysX systems officially, but admits modified drivers as opportunity for users to achieve desired result.

Q: Why do we need both v1.03 and v1.04ff, which should I use?A: If you are not going to use anything older than 257.21 – forget about v1.03 and usev1.04ff. The mod v1.03 is intended for old 19x series and 9.10.0222 (+older) PhysX SS.

If you update any component from the [old] 19x.xx and/or 9.10.0222 (+older) to [newer] 256 series and/or 9.10.0223 (+newer) – you should apply the mod v1.04ff afterwards. The mod v1.04ffwill not help with 19x series GeForce driver.

I’m seriously amazed… seems like you are right! I just didn’t test it yesterday because i saw a user report saying otherwise on another site, but now i’ve tested it by myself on Windows XP and Windows 7 x64 – it really works “out of the box” with 257.15.

In Windows XP i’ve just extended the fake desktop, and on Windows 7 i created one non-extended – that’s all i needed to get GPU-PhysX working. And even more surprising – timebomb issue is gone too, at least for its normal time interval (~30 seconds in FluidMark).

The fact remains that the investment to do a full QA cycle on this AMD/NVIDIA hybrid GPU configuration is beyond what NVIDIA can support at this time. The cost of maintaining AMD/NVIDIA hybrid configurations is larger than the development expense for PhysX, and I do expect that there are games and configurations where this type of system just won’t work.

DESCRIPTION:
This mod will enable hardware PhysX support for NVIDIA GPU, when non-NVIDIA GPU is used as a primary display device.
- intended only for WDDM 1.1 OS (Windows 7) and NT5 WDM OS (Windows XP/2003).
- only for multi-vendor multi-GPU configurations.

VERSION HISTORY:

1.03 – 21/04/2010:
- added support for fixing a timebomb, introduced in 196.75 and 197.xx drivers (gravity reverse + overall slowdown after a few seconds of PhysX processing)
- mod will now attempt to patch PhysX System Software files (helps to eliminate desktop extension requirement on Windows 7)
- mod will now disable “nvsvc” service autostart (helps to fix problems with fake displays)
- improved patching process (no more need to reboot in Safe Mode or terminate any process)
- improved patching logic (mod will no more try to patch non-existent files)
- improved accuracy of some patterns to avoid unnecessary patching

Q: Is there a virus/trojan/malware inside? My security software thinks so.
A: Your security software can make mistakes and thus is unreliable, just like any other security software. There are no such thing here.

Update #2:257.21WHQL GeForce Driver and 9.10.0223 PhysX System Software are not working with 1.03 mod.

Result can’t be called a “patch” anyway. This package contains several unmodified (unpatched) files from PhysX SS v9.09.1112 and v9.10.0129. While this can’t be a proper solution for newer versions of PhysX SS, i’m surprised it worked for people
